Abstract
A series of experimental tests were carried out to study and assessment of the geotechnical properties of the Fatha formation rocks in the Zurbatiyah region in eastern Iraq, the physical and mechanical characteristics have been studied in the study area of two types of rocks are represented by gypsum and limestone rocks. The physical results and tests helped to explain the mechanical behavior of the rock specimens that were studied. Several destructive and non-destructive tests were conducted on rock samples collected from various zones. Uniaxial compressive strength, point load, and Brazilian tests were tested on 60 intact rock specimens. The results of uniaxial compressive strength show that the maximum value of the compressive strength of the gypsum specimens was 35.08 MPa, while the maximum value in limestone specimens, was 38.095 MPa. In the indirect point load test, the maximum point load strength index IS(50) was 2.810 and 6.428 MPa for gypsum and limestone rock specimens respectively. In the indirect Brazilian test, the maximum tensile strength (σt) values were 4.66 and 7.36 MPa for gypsum and limestone rock specimens respectively. A new correlation with a high value of the regression coefficient R2 is presented, linking the uniaxial compressive strength (UCS) versus the rebound number of the Schmidt hammer (N).
期刊介绍:
Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas.
Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
